Tran Group - Haemostasis and Thrombosis
Research overview | Our people | Contact | Projects | Publications
Research overview
For patients with bleeding disorders, devise comprehensive diagnostic algorithms including genetic testing & undertake translational research to bring novel therapeutics to patients.
For patients with thrombotic disorders, better define the incidence, natural history and clinical outcome of venous thromboembolism, better define optimal management of VTE patients, & explore factors influencing clinical outcomes.
We are dedicated to advancing scientific knowledge through collaborative research and innovative projects. Our team brings together passionate researchers from diverse backgrounds, united by a commitment to excellence and discovery. We work closely in collaboration with the Haematology Clinical Research Unit (CRU, Alfred Hospital) and undertakes focused correlative studies with emphasis on biomarkers and patient outcomes
Our group specialises in multidisciplinary research, combining expertise in science, and clinical-focused outcomes. We strive to make a positive impact by addressing real-world challenges, gaps in clinical care to foster creativity, and nurture the next generation of Australian researchers.
